Matsakaicin dumamar yanayi ( GWP ) shine zafin da kowane yanayi mai gurɓata yanayi ke sha a cikin yanayi, a matsayin nau'in zafi mai yawa wanda zai iya ɗaukar nauyin carbon dioxide ( CO ). GWP shine 1 don CO. Ga sauran iskar gas ya dogara da iskar gas da tsarin a lokaci.

Carbon dioxide dai-dai ( CO e ko CO eq ko CO -e) ana ƙididdige su daga GWP. Ga kowane iskar gas, shine yawan CO wanda zai dumama ƙasa gwargwadon yawan iskar gas ɗin. Don haka yana samar da ma'auni gama gari don auna tasirin yanayi na iskar gas daban-daban. Ana ƙididdige shi azaman adadin lokutan GWP na sauran gas. Misali, idan akace gas yana da GWP na 100, ton biyu na gas suna da CO e na tan 200.
